Abstract: The present invention is directed to a building panel having a laminate structure comprising a cellulosic layer; and a topcoat layer that is substantially impervious to ambient moisture. The topcoat layer comprises a sealant sub-layer, an intumescent sub-layer comprising an intumescent composition, and the sealant sub-layer is positioned between the cellulosic layer and the intumescent sub-layer such that the intumescent sub-layer is separated from the first major surface of the cellulosic layer by the sealant sub-layer. The resulting building panel exhibits superior flame retardancy resulting in a Class A fire rating, according to ASTM E-84.
